Question

A tensile load of 60KN is gradually applied to a circular bar of 4cm diameter and 5m long.If the value of E=2.0*10^5n/mm^2 determine:
(i).Stress in the rod
(ii).Stretch in the rod
(iii).Strain energy stored in the body

Answer 1

Answer:

Stress= load/ area = 60,000/ (π/4D²) = 47.746N/mm²

Step-by-step explanation:

so the correct option is (i)
